У меня есть следующий код, и я не могу обновить UpdatePanel. Есть идеи? Мне интересно, возможно ли сделать обновление с помощью метода async?Обновление сетки изнутри AsyncFileUpload uploadCompleted event
<asp:UpdatePanel ID="UpdatePanel2" runat="server" UpdateMode="Conditional">
<ContentTemplate>
<asp:DataGrid ID="dgFiles" runat="server" DataKeyField="ConfigurationFileId" AutoGenerateColumns="false" GridLines="None"
OnItemCommand="dgFiles_ItemCommand" Width="40%">
<Columns>
<asp:TemplateColumn>
<ItemTemplate>
<asp:Label ID="lblFile" runat="server" Text='<%#Eval("SourceFileName") %>'></asp:Label>
